INCUBATOR.

SPECIFICATION forming part of Letters Patent No. 714,596, dated November 25, 1902.

Application filed $eptemher 16, 1901. Serial No. 75,839. (No model.)

To all whom it nuty concern:

Be it known that I, ISAAC Moscow, acitizen of the United States, residing at Manheim, in the county of Lancaster and State of Pennsylvania, have invented new and useful Improvements in Incubators, of which the following is a specification.

This invention relates to certain new and useful improvements in incubators, the ob- I0 ject being to provide an incubator of simple and efficient construction, having means whereby it may be economically heated and the temperature automatically kept at the proper point; and the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claim.

In the drawings,-Figure l is a side elevation of an incubator em bodying the invention.

Fig. 2 is a front end elevation of the same. Fig. 3 is an elevation of the rear end of the structure. Fig. 4 is a horizontal section on an enlarged scale. Fig. 5 is a transverse vertical section. Fig. 6 is a bottom plan View of thewater-tank Fig. 7 is a central vertical section of the water-drum. Fig. 8 is a longitudinal vertical section of the incubator. Fig. 9 is a view in perspective of one of the egg-trays employed, and Fig. 10 is a perspective view of one of the boxes located below the egg-trays to receive the chickens.

Referring to the figures in the drawings, 1

designates the body of the incubator, which is preferably constructed of double thickness, 3 5 with the space between the partitions forming the walls filled with any suitable substance nonconductive of heat; but instead of dou-' vided with an elongated neck portion 4, projecting outwardly from one end of the casing, and I provide on the outer end of the neck portion a depending water vessel 5, which is of the same height as the neck and tank and arranged in the same plane therewith. Below the water vessel and secured thereto isa cone-shaped receptacle having a surrounding intermediate partitioned waterchamber 6, communicating with the water vessel 5 by means of openings 11, arranged in the bottom of the Water vessel 5. Centrally arranged within the inner wall of the intermediate waterchamber and surrounding the same is an enlarged opening whereby to form a heatingcompartment 7. Within this compartment I secure to the bottom of the 'water vessel 5 a series of obliquely-arranged radiating water-pipes 10. having their upper ends connected to openings in said bottom of said watervessel, so as to communicate therewith. To the lower end of these pipes I connect a drum 9, having a closed top and an open bottom, and within the side Walls of this drum I arrange openings which communicate with a chimney S, centrally connected to the water vessel 5,wherebythe products of combustion are allowed to pass through the openings of the drum and out through the chimney. The upper portion of the chimney is extended above the water vessel, and to the top of the chimney I provide a threaded cap-piece 13, having suitable perforations or openings 14 therein.

A spigot 15 is secured in the lower end of the tank-chamber 6 for removing the water from the tanks 2 and 5.

16 designates an openingin the neck 4 of the water-tank, by which means the tank may be filled, and 17 designates a cap therefor.

By the peculiar arrangement of the water vessel the water is readily heated and caused to flow through the neck 4 into the tank 3 in such a manner as to evenly distribute the heat in a satisfactory manner. In order that the Water-tank 3 may be readily removed from the incubator, I provide a removable cover 18, which may be secured in position in any preferred manner. Arranged about midway of the height of the body 1 in suitable guideways 19 are the egg-trays 20, formed, preferably, of wire-netting and provided with a series of transverse strips 21 at such distances apart as to receive eggs between them and prevent the same from coming in contact with one another. Arranged directly below the egg-trays and mounted in suitable guideways 21 is a series of boxes 22, which are adapted to receive the chickens after they have been hatched.

. The egg-trays are shorter than the boxes- 22, so as to leave a space for the chickens to pass through from the egg-trays. The eg, trays 20 are located so that they may he slid into the incubator when the doors 2 are open.

Through the upper side of the ends of the incubator is a series of openings 23, provided with swinging dampers 24. Arranged centrally in the top of the incubator is an opening provided with a damper or valve 25. The damper 25 is suspended upon a lever 26,which is pivotally mounted upon a fulcrum 27, secured to the top of the incubator. The tank 3 is provided with an opening 28, directly below the damper 25 for the ventilating-flue.

The damper 25 may be controlled in any suitable manner to regulate the circulation of heated air in theincubator, and thereby maintain an even temperature of air in the body; but I prefer to control it bya thermostat 29, such as illustrated in the drawings, and which consists of two or more strips of material, as vulcanite, anda metal secured together, and which have different expansive properties, and being secured together, as stated, will bend when subjected tosufticient heat. The inner end of the thermostat 29 is bent to form a double hook, as at 30, and is adapted to be secured in a casing 31, fastened to the under side of the tank 3. The free end of the ther mostat is fastened to a rod 34, which extends upwardly through the tank 3 and secured to the lever 26 of the damper 25 at one side of the pivot-point thereof.

To regulate the thermostat, I provide the rod 34 with a threaded portion and a nut 33, by means of which any degree of tension may be applied to the thermostat, which tension must be overcome before the valve ordamper may be opened Any undue increase of heat in the incubator will cause the thermostat to open the damper 25, which will reduce the temperature within the body sufficiently to prevent the overheating of the eggs.

Secured to the under side of the incubator beneath the water chamber 5 is a lampbracket frame 34?. Slidably mounted within the frame 34 is a shelf 35, which is adapted to receive the lamp. It will readily be seen that by this arrangement the shelf can be slid under the incubator.

,Having thus fully described my invention and without limiting myself to the precise construction and arrangement of the parts shown, I claim- In an incubator; the combination with the casing, a rectangular tank mounted thereon above the egg-chamber, an elongated neck connected to said tank and projecting outwardly therefrom at one end of the casing, a

depending water vessel suspended by said neck constructed of the same height as the neck and tank and arranged in the same plane therewith, of an intermediate water-chamber arranged below the water vessel and communicating therewith,a hollow heating-compartment located within the inner surrounding wall of the intermediate water vessel, a drum with radial water-pipes located in the hollow heating compartment having their upper ends secured to openings in the bottom of the water vessel so as to communicate therewith, a chimney or flue centrally secured to the water vessel and perforations in the body of said drum, substantially as specified.

In testimony whereof. I affix my signature in presence of two witnesses.

ISAAC MORROW.
